I have not heard the Hi-Tone, so cannot compare, but do have a Custom 225, and from what I understand the Reeves is not a direct copy of the Hiwatt design - enhancements have been made and some of these features are noteworthy - like a DI out that ifs after the output transformer in the circuit, an extra gain stage and selector switch for active basses, and the output transformer is tapped 2/4/8 ohms instead of 4/8/16 ohms/ The two ohm tap is a nice feature with so many 4 ohm cabs in use these days. I have also heard that the Reeves225 has been voiced slightly different than the original Hiwatt 200 watt, adding a bit more low end. All I can tell you is that the Reeves has no issues with a B string. These differences may apply to the Hi-tone, as it seems to be more of a Hiwatt replica.
I hope this helps .
